Where 48 VDC is the given control level, the choice of large directional valves thins out fast. The H-4WEH25E6X/6EG48N9TS2K4 runs on 48 VDC, passes up to 700 l/min at 350 bar maximum operating pressure and uses external pilot oil supply with internal return.

Application
The valve drives large cylinders in presses, lifting gear and rolling lines whose flow demand is far above size 10. It mounts on a size 25 subplate. Because pilot oil comes from outside, the pilot circuit has to stay pressurised even when the main circuit is unloaded.
Manufacturer
Bosch Rexroth lists the valve as R901026079 in product family H-4W.H... Curves and dimensions are given in data sheets RE 24751 and RE 07600-B.
